The automobile shock absorber composite bush comprises a bush body which is connected with a shock absorber body, an inner bush and a rubber basal body, wherein the rubber basal body is fixed on the external surface of the inner bush, and a plastic lining bush is fixed on the inner wall of the inner bush; at least one annular projection is arranged on the external surface of the rubber basal body, and an annular groove is formed on the inner wall of the bush body and is in fit installation with the annular projection; and at least two axial through holes are formed in the end face of a rubber layer.
Description
Technical field
The invention belongs to the vibration damper field in automobile component, refer to especially a kind of automobile absorber composite bush and use the vibration damper of this lining.
Background technique
In vehicle traveling process, particularly suspension system is subject to the impact generation vibrations such as road surface,, in order to overcome the vibrations in running process, improves comfort property, is widely used vibration damper in suspension system in existing automobile.The vibration damper of existing automotive field is with hydraulic damper, its working principle is when between vehicle body and vehicle bridge during vibrated generation relative movement, piston in vibration damper is by moving up and down, damping oil in the vibration damper chamber is flowing in another chamber from chamber through hole repeatedly just, at this moment, by the friction between hole wall and fluid and the intermolecular friction of fluid, vibration is formed damping force, thereby realize the damping purpose.
Rubber bushing is as the secondary shock-absorbing measure that connects vibration damper and suspension system, and between the automobile assembly and in the connection of the flexibility between leverage, rubber bushing extensively is used.The existing rubber bushing that adopts can be divided into three kinds of structures basically.The one, the gum lining, the 2nd, bonded metal inner tube type rubber bushing, the 3rd, the rubber bushing of metal inner/outer tube is arranged.Above three kinds of rubber bushings are all to utilize rubber layer alleviate to impact, but the phenomenons such as rubber layer is easy in long-term using process aging, wearing and tearing.And such lining all adopts interference fit to install, and rubber layer is prone to accumulation, press-fits not in place or rubber layer such as peels off at the phenomenon when press-fiting.Lining is easy in use occur that sideslip, inclination, eccentric wear or damping performance are poor, occurs relatively rotating even problem between the interference fit parts.
Chinese patent notice of authorization number: CN100510457C proposes the rubber-plastic composite bush technological scheme, its main technical schemes is, the rubber body is fixed on the outer cylinder surface of steel bushing, be fixed with plastic bushing in the endoporus of steel bushing, at least be provided with a ring annular groove on the outer cylinder surface at rubber body middle part, be provided with oil-return groove in the endoporus of plastic bushing.Being provided with of the technical program rubber bushing is beneficial to the interference assembling, also can avoid the problems such as lining sideslip, inclination and eccentric wear when press-fiting, also can automobile strenuous vibration or load when larger because being out of shape the excessive integrally-built destruction that causes, and friction can be lubricated, be reduced to the oil-return groove design, increases the service life.
But in this technique scheme,, because the groove type of rubber layer design and interference are installed, be filled with a certain amount of gas in groove, when heavy duty being arranged or shaking when violent, gas can impact rubber layer, destroys the intensity of rubber layer and damages the overall structure of lining.And under case of heavy load, rubber layer is likely peeled off with steel bushing, and plastic bushing also exists and steel bushing problem in relative rotation.
Summary of the invention
To be provided with gas in groove at rubber layer and can to have influence on the strength problem of lining in order to overcome to adopt, rubber layer and steel bushing are peeled off problem and plastic bushing and steel bushing and are relatively rotated problem, propose a kind of automobile absorber composite bush and automobile absorber technological scheme.
The present invention is achieved by the following technical solutions:
The automobile absorber composite bush, include the body, inner sleeve and the rubber matrix that are connected with the vibration damper body; Rubber matrix is fixed on the outer surface of inner sleeve, is fixed with plastic bushing on the inwall of inner sleeve; The outer surface of described rubber matrix is provided with an annular protrusion at least, is provided with on the inwall of body and coordinates the annular groove of installing with annular protrusion; Be provided with at least two axial through holes that run through on the end face of described rubber layer.
Axially be provided with groove in the annular groove of described body.
Outer surface in described inner sleeve is provided with independently projection or reticular structure.
The described through hole that runs through is for being symmetrical arranged, wherein the center of a pair of through hole be arranged at respectively the vibration damper body axis extend to after lining through the mid point of rubber matrix part line segment on.
The axial length of described plastic bushing, less than the axial length of inner sleeve, is provided with seal ring in the two ends inner sleeve of plastic bushing.
Be provided with oil-return groove on described plastic bushing inwall.
Be provided with the vibration damper of described automobile absorber composite bush.
The present invention's beneficial effect compared with the existing technology is:
1, by running through the design of through hole, when being given a shock or during heavy load, run through through hole have certain deformation with buffering to integrally-built pressure.
2, the groove design by in body, what effectively stoped rubber layer moves axially and has simplified installation procedure.
3, by independently projection or reticular structure at lining the outer surface of, in the sulfidation of carrying out inner sleeve and rubber layer, make the combination between inner sleeve and rubber layer more firm, not there will be the problem of peeling off of inner sleeve and rubber layer, effectively avoided relatively rotating problem.
